Overview of this book

The Yocto Project is a Linux Foundation workgroup, which produces tools (SDK) and processes (configuration, compilation, installation) that will enable the creation of Linux distributions for embedded software, independent of the architecture of embedded software (Raspberry Pi, i.MX6, and so on). It is a powerful build system that allows you to master your personal or professional development. This book presents you with the configuration of the Yocto Framework for the Raspberry Pi, allowing you to create amazing and innovative projects using the Yocto/ OpenEmbedded eco-system. It starts with the basic introduction of Yocto's build system, and takes you through the setup and deployment steps for Yocto. It then helps you to develop an understanding of Bitbake (the task scheduler), and learn how to create a basic recipe through a GPIO application example. You can then explore the different types of Yocto recipe elements (LICENSE, FILES, SRC_URI, and so on). Next, you will learn how to customize existing recipes in Yocto/OE layers and add layers to your custom environment (qt5 for example).

Project description – CPU temperature monitoring


The idea of this project is the creation of a web interface that allows, for example, monitoring of the CPU temperature.

To do this, we will use technologies such as HTML5 and nodejs. We will also have utilities available on the Raspberry Pi, such as vcgencmd.

In this project, we will use technical aspects, such as:

  • Websocket

  • Justgage

  • Nodejs

The idea here is not to explain these technologies, but to learn that they can be used in the Yocto Project.

Overview

The following diagram represents the project's structure:

Hardware/software requirements

You'll need the following hardware and software for this project:

  • A Raspberry Pi

  • A host PC

  • An SD card

  • SSH/SCP
